VIGORPETRO's Swing Type Check valve functions by allowing flow forces to move the closure element, it is a hinged clapper which swings or rotates around a supporting shaft.The disk swings away from the valve-seat to allow flow in the forward direction, and returns to the valve-seat when upstream flow is stopped, to prevent backflow. These valves produce the lowest pressure drop, when compared with other check valves of the same size, the internal contours and shapes allow them to fully open at low fluid velocities and create a smooth flow path through the valve.
♦ Center-of-gravity location of the disc and swing arm assembly designed in order to minimize pressure drop and suitable for vertical installation as standard: the valve will return to the closed position should flow become interrupted or reversed even with vertical installation (flow must be in an up-flow direction).
♦ Internal hinge pin design eliminates additional leakage points.
♦ High flow capacity port sizes and disc retraction to minimize flow velocities and maximize valve service life.
♦ Design of disc and hinge assembly to generate a closing moment to provide adequate closure and sealing at low pressures.
♦ Sealing surfaces are machined to the tightest tolerances and lowest roughness to ensure trouble free shut off and cycling.
♦ Low cracking pressure design.
♦ Swing check nut positively secured to prevent disassembly during service by permanent cold deformation of the closure member. No additional cotter pin or other small parts are used as locking system.
♦ Pressures up to 20,000 PSI for Various Sizes (1-1/13" to 7-1/16")
♦ Internal parts are completely interchangeable with OEM
♦ A wide range of body and trim materials to meet various operatingconditions
♦ Especially designed for Production and drilling applications
♦ Low maintenace operation
